(Quoting Launchpad:)
'emacs' is a binary package. This bug has been assigned to its source
package 'emacs22' instead.
The bug supervisor for emacs22 (Ubuntu) has been subscribed to this bug.
** Changed in: emacs22 (Ubuntu)
Status: New => Confirmed
** Description changed:
Binary package hint: emacs
+
+ Summary: the "emacs" metapackage has a confusing version number, and
+ some users expect it to pull in emacs23 rather than emacs22. In
+ particular, packages which depend on the "emacs" metapackage will pull
+ in emacs22 even if emacs23 is already installed. Perhaps the
+ description of the "emacs" package should be clearer about its being a
+ metapackage, and perhaps point to information about main vs. universe.
+
+ Original description follows.
After installation of Ubuntu 9.10RC, I installed emacs23 package but not
emacs package, and was additionally going to install w3m-el-snapshot
package which depends on emacs package. However, I stopped installing
w3m-el-snapshot because emacs package required to install emacs22
package by its dependencies:
$ sudo apt-get install w3m-el-snapshot

It seems as if the installation candidate of emacs package is the latest
version 23, but this package strangely depends on the older version 22:
$ apt-cache policy emacs

emacs package is described as follows:

- release.

I have read Bug #433397 and understand why emacs22 is installed prior
to emacs23. But I think the version number of emacs package and this
package description are very confusing.
